ObjectiveTo evaluate the efficacy of silodosin therapy, as a new α-adrenergic receptor (α-AR) blocker, on the success rate of semi-rigid ureteroscopy (URS) for the management of large distal ureteric stones.Patients and methodsThis prospective study recruited 127 adult patients with single distal ureteric stone of ≥1 cm. The patients were randomly allocated to two groups: the first group included 62 patients who received silodosin (8 mg) for 10 days before URS (Silodosin group), whilst the second group included 65 patients who received placebo, in the form of multivitamins, for 10 days before URS (Placebo group). All patients underwent URS and a pneumatic lithoclast was used for stone fragmentation.ResultsThe mean (SD) operative time was shorter in the Silodosin group compared with the Placebo group, at 41.61 (4.67) vs 46.85 (4.6) min, respectively. Furthermore, advancing the ureteroscope to access the stone failed in a statistically significant number of patients in the Placebo group compared with the Silodosin group (13 vs two, respectively). The complication rate was significantly higher in the Placebo group compared with the Silodosin group (20% vs 6.4%, P = 0.036). Additionally, the need for postoperative analgesia was significantly lower in the Silodosin group compared with the Placebo group (8.1% vs 26.2%, P = 0.009).ConclusionSilodosin therapy prior to URS management of large distal ureteric stones seems to be associated with better advancing of the ureteroscope to access the stone, shorter procedure time, higher stone-free rate, lower incidence of complications, and lesser need for postoperative analgesia.
ObjectiveTo prospectively compare the outcome of standard mini-percutaneous nephrolithotomy (SmPCNL) versus tubeless mini-percutaneous nephrolithotomy (TmPCNL) as primary treatments of renal stones.Patients and methodsIn all, 80 patients with a solitary radio-opaque renal stone and candidates for PCNL were selected. The patients were randomly divided into two groups of 40, one group treated with SmPCNL and the other with TmPCNL. Patients and stone characters, as well as operative and postoperative data of both groups were compared and statistically analysed.ResultsThere was no significant difference between the two groups for patient demographics and stone characteristics. There was no statistically significant difference between the two groups for the mean operative time, mean postoperative drop in haemoglobin, mean postoperative urine leakage, mean hospital stay, and stone-free rate. The mean (SD) postoperative dose of analgesia was statistically significantly higher in the SmPCNL group compared with the TmPCNL group, at 112.5 (48.03) versus 48.8 (43.5) mg, respectively.ConclusionBoth procedures are safe and effective for managing renal stones, without any significant difference between the two procedures; however, the postoperative analgesic requirement is significantly higher in SmPCNL.
SWL is less invasive than percutaneous stone removal, but it is also less effective for lower pole radiopaque calculi. Miniperc has better SFR and lower auxiliary and retreatment rates; however, it resulted in more drawbacks.
Objective: To compare the efficacy and safety of silodosin against tamsulosin as medical expulsion therapeutic agent in stone lower 1/3rd ureter. Patients and Methods: One hundred fifty patients divided equally into 2 groups I and II received silodosin 8 mg and tamsulosin 0.4 mg respectively. Patients aged 18 years or older having single unilateral stone 10 mm or less were included in the study. Patients with bilateral or multiple stones, marked hydronephrosis, previous open or endoscopic surgery and having urinary infection were excluded. Patients were followed weekly for 4 weeks by ultrasonography, plain radiography of the urinary tract and CT of the urinary tract when indicated. Results: Silodosin showed better results against tamsulosin as stone expulsion rate in silodosin and tamsulosin groups was 82.4 and 61.5% respectively with significant difference (p = 0.007). Also, the stone expulsion time was significantly lower in silodosin against tamsulosin groups as it was 9.4 ± 3.8 vs. 12.7 ± 5.1 days in group I and II respectively (p = 0.001). The adverse effects were comparable with non-significant more retrograde ejaculation in the silodosin group. Conclusion: Silodosin showed better efficacy in the stone expulsion rate and time with comparable safety of both drugs, with nonsignificant more retrograde ejaculation in silodosin.
